What kind of cable is YJV22? Comprehensive analysis of structure and uses
In power transmission and distribution systems, cable selection is critical. As a common power cable, YJV22 cable is widely used in various engineering projects. This article will introduce in detail the structure, characteristics, technical parameters and applicable scenarios of YJV22 cable, and attach an analysis of the hot topics on the entire network in the past 10 days.
1. Basic definition of YJV22 cable
YJV22 is aCross-linked polyethylene insulated steel tape armored PVC sheathed power cable, which is a type of armored cable. The meaning of the code in its name is as follows:
| code name | meaning |
|---|---|
| YJ | Cross-linked polyethylene insulation |
| V | PVC sheath |
| 22 | Double steel belt armored |
2. Structural characteristics of YJV22 cable
The cable adopts a multi-layer protection design, and its specific structure is as follows:
| structural layer | Material/function |
|---|---|
| conductor | Copper or aluminum (commonly copper core) |
| insulation layer | Cross-linked polyethylene (XLPE) |
| Inner sheath | Polyvinyl chloride (PVC) |
| Armor layer | Double steel belt wrapping |
| outer sheath | Polyvinyl chloride (PVC) |
3. Technical parameters and performance advantages
The main technical indicators of YJV22 cable are as follows:
| Project | parameters |
|---|---|
| Rated voltage | 0.6/1kV to 26/35kV |
| Long-term operating temperature | 90℃ |
| short circuit temperature | 250℃ (duration ≤5 seconds) |
| bending radius | ≥15 times cable outer diameter |
| Laying conditions | Direct burial, pipelines, tunnels, etc. |
Its core advantages include:
1.Strong mechanical protection: Steel tape armor can resist external damage
2.Good corrosion resistance: PVC sheath adapts to various environments
3.High carrying capacity: Cross-linked polyethylene insulation with excellent temperature resistance
4. Application scenarios and selection suggestions
Typical application fields of YJV22 cable:
| scene type | Specific applications |
|---|---|
| Electric power engineering | City power grid and substation outlet |
| Industrial field | Factory power distribution and equipment power supply |
| construction project | Underground cable trench laying |
| special environment | Humid, dusty, mechanical pressure places |
5. Association analysis of recent hot topics (last 10 days)

| Copper price fluctuations | high | Impact on cable raw material costs |
6. Comparison between YJV22 and ordinary cables
Differences compared to YJV (non-armored) cable:
| Comparative item | YJV22 | YJV |
|---|---|---|
| Protection level | IP56 | IP44 |
| stress tolerance | Withstands mechanical stress | Stress-free environment only |
| Laying method | Direct burial/pipe penetration | Bridge/overhead |
| price | About 15-20% higher | Basic price |
Summary:YJV22 cable has become the preferred solution in complex environments due to its armored protection properties. Demand continues to grow in hot areas such as new energy infrastructure and urban renovation. When purchasing, you need to consider comprehensive considerations based on the actual laying environment and budget. It is recommended to pay attention to new industry standard trends and raw material price trends to obtain the best cost performance.
